Hi @PoojithaVap ,

Can you please explain how previous and current objects work, and which objects are accessible in each business rule(After, Before, Async, Display) 

Answer: 

business rule execute when CRUD operations happen on any record.

When before and After Business rule is running it gets two copy of the record which is changed.

Previous is a copy of same GlideRecord object storing old values (Original copy)

Current is copy of GlideRecord object storing New values (Updated copy)

For Example:

When you opened any incident it was having state as new and Assigned to empty (This will be your Previous copy). Now you changed state and assigned_to fields and saved form (This is updated i.e current copy).

If you try to log below lines for above example :

gs.info(previous.state);  // it will print new (i.e 1)

gs.info(previous.assigned_to);  // it will print nothing (assihnedto was empty)

gs.info(current.state);  // it will print In Progress (i.e 2)

gs.info(current.assigned_to);  // it will print sys_id of assigned_to user

Which of the following is NOT a Flow Designer feature?

D. Test a flow using the “Run as” feature

What data types of Flow Variables are supported to store record data? (Choose three.)

For Async and Display business rule there is no access to previous object right?
